Figure 2-4
Using a 100Mbps transceiver module to provide a 100Mbps network
connection, gives you several options:
You can have a fast downlink to a network server or the rest of
your network.
You can connect a 100Mbps network to your 10Mbps network,
allowing you to migrate to a faster network in the future.
With multiple PS Hub 50 units, you can have a Fast Ethernet resilient
link in your stack, refer to "Fast Ethernet Resilience" on page 2-5.
